The Millennium Bell was recorded between February and October 1999. Mike's idea of marking the division between the centuries came from the use of Big Ben at the end of the Tubular Bells III premiere concert.

The bell heard in the title track is a combination of several bell sounds, which was specially created for this album by Roland, the company which makes some of the instruments Mike uses.

The orchestral pieces on this album, Lake Constance and Broad Sunlit Uplands, were recorded in Abbey Road Studio One.
